Subject: Parallel FFT Packages
I am trying to gather information about parallel FFT packages. I am
particularly interested in the following:
# of dimensions supported
types of data decomposition supported
parallelization implementation (MPI, OpenMP, CUDA, OpenCL,...)
type of FFT (real-to-complex, complex-to-real, complex-to-complex)
precision (single, double, both,...)
native language(s) that the package is written in; support for
bindings to other languages
underlying 1D FFTs supported (FFTW, vendor provided,...)
Does the package support auto-tuning?
Can a user control the direction (forward, backward, none) of the
individual dimensions in a multi-dimensional FFT?
Does the package support MPI subgroups of processors?
Does the package support user access to routines that transpose arrays
and redistribute data?
Is the package actively supported? if so, how (via email, wiki, google
group, ...)
URL of the package
FFT packages I am already aware of that have parallel capability are:
http://www.fftw.org/
http://www-user.tu-chemnitz.de/~mpip/
http://www.sdsc.edu/us/resources/p3dfft
http://www.ffte.jp/
http://www.2decomp.org/
http://www.sandia.gov/~sjplimp/docs/fft/README.html
Besides these, if you have developed or use an open-source,
documented, parallel FFT package, I would appreciate it if you would
send me email about it (RDRyne@lbl.gov)
On a separate but related topic, I would like to hear from people who
have written their own parallel FFT packages, and why they did it.

Subject: Software for Structured Low-Rank Approximation (SLRA)
The SLRA package computes locally optimal solutions to low-rank
approximation problems with the following features:
- mosaic Hankel structure constraint on the approximating matrix,
- weighted 2-norm approximation criterion,
- fixed elements in the approximating matrix,
- missing elements in the data matrix, and
- linear constraints on an approximating matrix's left kernel basis.
The code is written in C++ and can be called from Matlab, Octave, & R.
Some applications of the package are:
- maximum likelihood system identification,
- optimal model order reduction,
- spectral estimation,
- approximate deconvolution,
- approximate common divisor computation.
For more information, see:

The package is available from:

Subject: New Book, Solving PDEs in C++, Second Edition
Announcing the June 6, 2012, publication by SIAM of:
Solving PDEs in C++: Numerical Methods in a Unified Object-Oriented
Approach, Second Edition, by Yair Shapira
June 2012 / xxxii + 765 pages / Softcover / ISBN 978-1-611972-16-0 /
List Price $139.00 / SIAM Member Price $97.30 / Order Code CS09
In this much-expanded second edition, author Yair Shapira presents new
applications and a substantial extension of the original
object-oriented framework to make this popular and comprehensive book
even easier to understand and use. It not only introduces the C and
C++ programming languages, but also shows how to use them in the
numerical solution of partial differential equations (PDEs).
New material in this edition includes new chapters on 3-D nonlinear
applications and image processing applications; new sections on
cryptography applications; and even more new sections, many including
additional algorithms.
The book is written for researchers, engineers, and advanced students
who wish to increase their familiarity with numerical methods and to
implement them using modern programming tools. It can be used as a
textbook in courses in C++ with applications, C++ in engineering,
numerical analysis, and numerical PDEs at the advanced undergraduate
and graduate levels. Because it is self- contained, the book is also
suitable for self-study by researchers and students in applied and
computational science and engineering.

Subject: Professor/Reader/Lecturer Positions, Univ of Sussex
Responding to increasing student numbers and repeated research funding
successes the Department of Mathematics at the University of Sussex is
expanding and therefore invites applications for three positions in
Mathematics.
In the 2008 research assessment exercise (RAE), 90 per cent of our
research activity in Mathematics was rated as being internationally
recognised or higher. The Times Higher Education ranking placed the
University of Sussex 99th in the world and 12th in the UK, Mathematics
at Sussex was ranked 11th and 17th in the UK in two recent league
tables (Guardian 2012, Complete University guide 2012). It also
repeatedly scores well in the UK National Student Survey.
The Department is currently organized into the three areas: Analysis
and PDEs, including Financial Mathematics; Mathematics Applied to
Biology; Numerical Analysis and Scientific Computing. However strong
applications from all fields of Mathematics including Probability and
Statistics are strongly encouraged and will be given full
consideration. Candidates should have outstanding academic
credentials, a proven track record of world-leading research and will
be expected to show leadership in the generation of research. In
addition, professorial candidates are invited to set out a case for
attaching a lectureship to their field of research.
Closing date for applications: 31 July 2012
Interview date: first half of September
Informal enquiries may be made to the Head of Department, Prof. Erik
Burman (e-mail E.N.Burman@sussex.ac.uk Tel 01273 678933).
